I had another thought today,(I really should be carefull), and that was what if for obstacle detection and sensor input you used three input devices (you pick) then ran the inputs into a comparator circuit. The output of the comparator would then be sent to the CPU or controller device. Statistically this should inhibit the chances of random noises or light from confusing our mechanical friends. Especially if you used three or more inputs and offset the level that the sensors were lined up on. Example use an isocolese (I know that is spelled wrong, but hey it's public education for you!) triangle or hex patern. If you got any thoughts on if this would be a feasible alternative to more exspensive sensors and detection systems... please let me know. jaltop@stmartin.edu

Just a thought: one of the problems i see with reducing the weight of the robots power system is that there needs to be enough electrically energy to power and sustain the unit for x amount of time. this ussually involves one large battery or several small ones. the weight of this adds together and requires the drive motors to need more torque to move the heavier system containing all those batteries. But what if you were to use two rechargable batteries and a solar collector, a few relays and possible a comparator or time to do this: have one battery just large enough to supply the motors with enough energy for movement for x amount of time. the second battery will be charged by the soloar cell for y amount of time. When the first battery is low, a comparator, timer or relay will actuate and switch the system to the second battery which should by now be charged. The same switching then transfers the charging process to the first battery, while the robot continues on with objective. i see a few bugs in this system myself right now, but any thoughts you mighthave....
